How it's used
Functions as a conditional conjunction that introduces an alternative or a consequence. It is frequently used to present a threat or a warning about what will happen if a specific action is not taken. When used in a pair, it creates an either-or structure that emphasizes a choice between two distinct possibilities.
Examples
You better leave quickly, otherwise you will be late.

Common mistake
Do not confuse this with 或者, which is used for neutral suggestions. 一唔係 carries a stronger sense of urgency or a binary choice where one option is often undesirable.
